vomiting after ejaculation???

hi. My partner is 38, and usually a fit and healthy man. he's 6ft and weighs approx 11stone. He hasn't had many medical problems, but this one has appeared in the last few months.. After intercourse (after ejaculation) he gag's and then vomits...most of the time. sometimes he can control it..usually a drink of water helps. I'm not sure if this is serious but ive been with him 5 years and its never happened unitl recently.does anyone know what this is, any causes, treatment or any experience of this.?i'd be very grateful for any help. thank you so much.
